Product Description

The 140CHS11000 is a Hot Standby (HSBY) synchronization module for the Modicon Quantum by Schneider Electric. It enables real-time data mirroring between a "Primary" and a "Standby" CPU, ensuring continuous operation and bumpless failover in mission-critical applications.

This module uses a dedicated high-speed fiber optic link to offload redundancy communication from the main network. Paired with Unity HSBY CPUs (e.g., 140CPU67160), it allows two identical racks to maintain synchronous process data, making it ideal for fault-tolerant architectures in oil & gas, power generation, and water treatment plants.

Technical Specifications

Application Scenarios

The 140CHS11000 is used where CPU downtime is unacceptable:

  • Emergency Shutdown Systems (ESD)

  • Boiler and turbine control in power plants

  • Chemical batch and continuous processing

It allows the standby rack to take over in less than one scan cycle if the primary fails.

FAQ

Q1: What type of fiber optic cable is required?
Standard 62.5/125 µm or 50/125 µm multimode fiber with MT-RJ connectors.

Q2: Can it be used with any Quantum CPU?
No. Only CPUs supporting Hot Standby functionality (Unity HSBY processors) are compatible.

Q3: What is the maximum distance between redundant racks?
Up to 2 km using standard multimode fiber, allowing placement in separate fire zones.
